Description
Technical field
The present invention relates to the marine mobile platform bucket base in a kind of ocean engineering field, be specially adapted to the exploitation of marginal oil field.
Background technology
Existing light-duty marine mobile platform is not furnished with Fuel Tanking Unit basically, need after platform recovers the oil shuttle tanker frequent back and forth between oil field and land to realize the conveying of crude oil, cause the waste of human and material resources, increased the running cost of oil field development, reduce the rentability of marginal oil field greatly, be unfavorable for the exploitation of isolated small oil field.Simultaneously, the ocean surface Fuel Tanking Unit very easily has an accident when running into bad weather or other extraneous force majeure, causes crude oil leakage, brings serious pollution to surrounding environment.In addition, generally, specially treated is not carried out in the bucket base of marine mobile platform bottom.When platform on more smooth sea bed immediately, traditional bucket base can meet the demands.But when rock or bigger fluctuations appear in sea bed bottom, use general basis to be difficult to the stability requirement of implementation platform.
Summary of the invention
The objective of the invention is to by traditional bucket base structure is transformed, the function that makes bucket base possess oil storage simultaneously and install certainly, and improve the barrel shape reliability of structure.
The technical solution used in the present invention is as follows:
A kind of self-mounting type bucket base that has oil storage chamber, comprise oil storage chamber, anchor tube, column, vent line, it is characterized in that being fixed with oil storage chamber on described anchor tube top, described oil storage chamber is made of top board, double walled floor and double Shell, on the top board of described oil storage chamber, have into and out of oilhole, the double walled floor that described vent line passes oil storage chamber stretches in the anchor tube.
In technique scheme, anchor tube lower end is preferably sawtooth pattern; Oil storage chamber preferably is provided with subdivision, and on each bulkhead reinforcement in length and breadth is set preferably; Described oil storage chamber is provided with the subdivision more than three or three, described fuel feed hole is opened on the top board on the first subdivision top, first subdivision is adjacent with second subdivision, second subdivision is adjacent with the 3rd subdivision, adjacent until last subdivision with first subdivision, the sealing, the lower end of all the other Divisional Bulkheads all offers intercommunicating pore between the Divisional Bulkhead between first subdivision and last subdivision.
Superiority of the present invention is:
1, bucket base top has an airtight oil storage chamber, can satisfy the oil storage demand of marine mobile platform short-term, avoids shuttle tanker frequently to come and go the increase of the operating cost of bringing, and is specially adapted to exploit the marginal oil field in zone, the Bohai Sea.
2, oil storage chamber is partitioned into subdivision by Divisional Bulkhead, can improve its structural strength, has intercommunicating pore in the Divisional Bulkhead lower end simultaneously, is easy to crude oil and flows between the cabin.
3, oil storage chamber adopts double Shell and double-deck bilge structure, in case the breakage of oil storage chamber inner panel, crude oil will can directly not flow out and pollute, and increase certain repairing time to the maintenance personal, makes loss drop to minimum as far as possible;
4, oil storage chamber uses as ballast tank in installation process, and bottom anchor tube is realized the installation certainly of bucket base, reduces installation cost;
5, the bucket base bottom is a zigzag, improves the bucket base reliability, and satisfies different submarine soil layer requirements;
6, the member that is adopted among the present invention is standardized structural element, need not special manufacturing, thereby saves the engineering manufacturing cost greatly.

The specific embodiment
Below in conjunction with drawings and Examples the present invention is further described.
The marine mobile platform bucket base of self-mounting type that has oil storage chamber of the present invention is made up of oil storage chamber 2, anchor tube 1, column 4, vent line 3.Bucket base top has an airtight oil storage chamber 2, by Divisional Bulkhead 13,14,15,16, can be divided into a plurality of subdivisions, to reach the requirement of strength of structure.Its effect is to provide self-buoyancy for the bucket base towage under Light Condition; Erection stage can be used as ballast tank; The platform production phase is realized the oil storage function by oiling in the cabin, saves the dealing cost of transportation.Have into and out of oilhole 11,12 on the oil storage chamber top board.Oil storage chamber is a double Shell 5, prevents crude oil leakage, its center drilling, so that vent line 3 therefrom passes, the bilge 6 is seated on the top cover of anchor tube.Reinforcement in length and breadth is set on the bulkhead.And the bucket base bottom is an anchor tube 1, by exhaust decompression in 3 pairs of tubes of vent line, forms anchor top pressure reduction up and down, realizes the suction injection.Anchor tube 1 be zigzag bottom, make the engagement of bucket base and submarine soil layer, fully improved marine mobile platform and propped up immediately degree of safety, go into the resistance of can reducing friction in the mud process at bucket base simultaneously, accelerate to go into mud speed.This bucket base that has an oil storage chamber is compared with the bucket base of traditional no oil storage chamber, its superiority is to satisfy the platform oil storage demand of short-term, the overall process that can realize self-floating towing, sink smoothly, injection does not fast rely on crane ship from installation, and can be used for complicated seabed.The present invention provides a kind of platform base of economic and reliable to the exploitation of marginal small oil field.
Before installation, bucket base and column are assembled, wherein anchor tube 1 is stretched into by air vent 10 in vent line 3 lower ends, and the upper end is passed the aperture of having held successfully column 4 bottoms and is led to centrifugal pump, in order to extracting the usefulness of anchor tube 1 maritime interior waters in the installation process out.
Concrete installation steps are:
(1) oil storage chamber emptying state in bucket base top is realized down self-floating towing, and condition is the gravity that buoyancy that oil storage chamber 2 provides is enough to balance bucket base structure.
(2) to place in place, open the fuel feed hole 11 on the oil storage chamber top board, seawater is charged into oil storage chamber, realize the stable sinking of bucket base, insert the seabed until bucket base and reach the initial sealing desired depth.
(3) open gas valve, the seawater of anchor tube inside, bucket base lower end is discharged by vent line 3, realize the suction sinking, the anchor tube sinks fully until the bucket base lower end, and the degree of depth just is an anchor tube height, and oil storage chamber remains on more than the soil layer.
(4) open oil outlet 12 on the oil storage chamber, and close fuel feed hole 11, with cabin maritime interior waters emptying, installation process finishes by centrifugal pump.
(5) begin to recover the oil after installation finishes.The crude oil of adopting enters oil storage chamber by fuel feed hole 11.Crude oil flows to second subdivision through first subdivision by intercommunicating pore 17, is full of four subdivisions until crude oil.Intercommunicating pore is not established in Divisional Bulkhead 16 bottoms between first subdivision and the 4th subdivision, prevents that crude oil from flowing backwards.
(6) crude oil is extracted oil storage chamber by oil outlet 12 out by centrifugal pump after being full of oil storage chamber, connects flowline then and leads in the oil storage tank of working ship.Crude oil is at first carried outward from the 4th subdivision, and the crude oil in its excess-three cabin flows to the oil storage tank of shuttle tanker equally through flowing to the 4th subdivision into and out of oilhole 17 through flowline, thereby realizes the reverse flow of crude oil.
